Text detection and segmentation system serves as important method for document analysis as it helps in many content based image analysis tasks. This research paper proposes a connected component technique for text extraction and character segmentation using maximally stable extremal regions (MSERs) for text line formation followed by connected components to determined separate characters. The system uses a cluster size of five which is selected by experimental evaluation for identifying characters. Sobel edge detector is used as it reduces the execution time but at the same time maintains quality of the results. The algorithm is tested along a set of JPEG, PNG and BMP images over varying features like font size, style, colour, background colour and text variation. Further the CPU time in execution of the algorithm with three different edge detectors namely prewitt, sobel and canny is observed. Text identification using MSER gave very good results whereas character segmentation gave on average 94.572% accuracy for the various test cases considered for this study.

Four formulations of chicken burger were prepared: control product without inulin, and products with 1.0, 2.0 or 3.0 % of inulin (in relation to the weight of meat, fatty raw material, and water), respectively. Physical, chemical and sensory analyses were made to evaluate the effect of inulin on the quality of cooked burgers. The results showed that the application of inulin did not cause significant decrease of the thermal processing yield nor the shear force of the products. However, the addition of inulin resulted in slight, but significant differences (P < 0.05) in chemical composition and energy value of burgers. Burgers of all formulations were acceptable in sensory characteristics. The addition level of inulin not higher than 1.0 %, did not result in deterioration of physical, chemical and sensory quality characteristics of chicken burgers. To improve the nutritional value of chicken burgers, the modification of fatty acid composition is recommended.

Flood Fill

In many documents such as maps, engineering drawings and artistic documents, etc. there exist many printed as well as handwritten materials where text regions and text-lines are not parallel to each other, curved in nature, and having various types of text such as different font size, text and non-text areas lying close to each other and non-straight, skewed and warped text-lines. Optical character recognition (OCR) systems available commercially such as ABYY fine reader and Free OCR, are not capable of handling different ranges of stylistic document images containing curved, multi-oriented, and stylish font text-lines. Extraction of individual text-lines and words from these documents is generally not straight forward. Most of the segmentation works reported is on simple documents but still it remains a highly challenging task to implement an OCR that works under all possible conditions and gives highly accurate results, especially in the case of stylistic documents. This paper presents dilation and flood fill morphological operations based approach that extracts multi-oriented text-lines and words from the complex layout or stylistic document images in the subsequent stages. The segmentation results obtained from our method proves to be superior over the standard profiling-based method.

Excursion Set

The distribution of the size of one connected component and the largest connected component of the excursion set is derived for stationary χ2, t and F fields, in the limit of high or low thresholds. This extends previous results for stationary Gaussian fields (Nosko 1969, Adler 1981) and for χ2 fields in one and two dimensions (Aronowich and Adler 1986, 1988). An application of this is to detect regional changes in positron emission tomography (PET) images of blood flow in human brain, using the size of the largest connected component of the excursion set as a test statistic.

Internationalization Of Education

For a long time French and English compete in international life. Globalization has led to the internationalization of education. With the desire of universities to become international universities, the position of foreign languages, such as English, French, German, Japanese become more important. In France as in other countries one of the most important languages is English. Hagège says that to impose one&#39;s language is also to impose one&#39;s thought. It seems that France is becoming more open to English. In addition to the growth of foreign languages, it is necessary to consider the consequences of internationalization for cultural preservation, the prestige of the national language, linguistic and cultural diversity and the quality of the university. Fioraso, the former French education minister, has published a law that is considered unacceptable for higher education unions. On May 22, 2013 teachers-researchers and students were mobilized, against the project of reform higher education examined at no charge by the National Assembly. Teachers-researchers and students were mobilized on Wednesday, May 22, to protest against the proposed reform of higher education examined at no charge by the National Assembly. In general, researchers who evaluate the internationalization of higher education tend to share the idea that internationalization opens opportunities that are more desirable than dangerous. This article discusses the influence of English, because of the internationalization of education in France and the domination of the United States. These two colonial languages continue to compete and the widespread use of English has been rejected by some people. Both have some prestige, English is Shakespear&#39;s tongue of a coast and French is the language of Molière.

Good Learning

National character and civilization building cannot be separated from the education institution. As a place for producing intellectuals, education institutions might be regarded as the “second homes” in which students study to develop their competencies. They are the places in which the collaboration from the students’ parents is needed in order to create a good learning atmosphere. So far the Hindu education institutions receive lack of this kind of collaboration. As a solution, it is necessary to provide more space for the students’ parents to contribute to the Hindu higher education improvement. Such a place is necessary for a good communication as in a particular situation students’ parents should be involved in improving the quality of the education and avoiding opposition.

Performance Results

Recent advances in medical imaging analysis, especially the use of deep learning, are helping to identify, detect, classify, and quantify patterns in radiographs. At the center of these advances is the ability to explore hierarchical feature representations learned from data. Deep learning is invaluably becoming the most sought out technique, leading to enhanced performance in analysis of medical applications and systems. Deep learning techniques have achieved great performance results in dental image segmentation. Segmentation of dental radiographs is a crucial step that helps the dentist to diagnose dental caries. The performance of these deep networks is however restrained by various challenging features of dental carious lesions. Segmentation of dental images becomes difficult due to a vast variety in topologies, intricacies of medical structures, and poor image qualities caused by conditions such as low contrast, noise, irregular, and fuzzy edges borders, which result in unsuccessful segmentation. The dental segmentation method used is based on thresholding and connected component analysis. Images are preprocessed using the Gaussian blur filter to remove noise and corrupted pixels. Images are then enhanced using erosion and dilation morphology operations. Finally, segmentation is done through thresholding, and connected components are identified to extract the Region of Interest (ROI) of the teeth. The method was evaluated on an augmented dataset of 11,114 dental images. It was trained with 10 090 training set images and tested on 1024 testing set images. The proposed method gave results of 93 % for both precision and recall values, respectively.

Efficiency And Reliability

Huge and reputed software industries are expected to deliver quality products. However, industry suffers from a loss of approximately $500 billion due to shoddy software quality. The quality of the product in terms of its accuracy, efficiency, and reliability can be revamped through testing by focusing attention on testing the product through effective test case generation and prioritization. The authors have proposed a test-case generation technique based on iterative listener genetic algorithm that generates test cases automatically. The proposed technique uses its adaptive nature and solves the issues like redundant test cases, inefficient test coverage percentage, high execution time, and increased computation complexity by maintaining the diversity of the population which will decrease the redundancy in test cases. The performance of the technique is compared with four existing test-case generation algorithms in terms of computational complexity, execution time, coverage, and it is observed that the proposed technique outperformed.
